Feed crushing and screening device

Abstract

The present invention discloses a feed crushing and screening device, which involves a variety of feed crushing technical fields, including a return device, a crushing device, an inspection cover, a dust suction component, a material suction component, a clamping component, a vibrating screen component, and a first belt. In the crushing device, the vibrating screen component lifts the feed particles upward, and then vibrates the feed particles through the vibrating screen slide, so that the deflated particles and dust fall from the vibrating screen bottom plate, and then the dust and deflated particles are sucked out by the dust suction component to achieve the preliminary screening function before crushing. The first worm on the crushing device drives the first vertical roller and the first horizontal roller to rotate synchronously through the first worm wheel and the third belt respectively, so as to achieve the synchronous crushing function. The vibrating component, through the obstruction effect after the vibrating screen bottom plate contacts with foreign objects, causes the pressure to be transmitted from the vibrating screen bottom plate to the clamping component. At this time, the electric push rod of the clamping component rebounds, so that the vibrating screen bottom plate can rotate freely on the fixed plate, thereby realizing the functions of preventing hands from being stuck and preventing foreign objects from being stuck.

Description

Technical Field

[0001] The present invention relates to the technical field of feed crushing, and in particular to a feed crushing and screening device. Background Art

[0002] In the process of feed production, corn kernels need to be stuffed into the crusher for crushing, and then the corresponding nutrients and additives are added and mixed evenly according to the corresponding needs; the degree of feed crushing is one of the most important determinants of feed quality; therefore, the crushing process needs to be reasonably arranged according to the particle size and hardness of the feed.

[0003] The existing feed crushers generally adopt a roller pressing method to crush the feed. This method is simple, efficient, and easy to maintain. However, the simple roller pressing method cannot achieve complete crushing of the feed. In the crushing process, corn particles that cannot be crushed will remain. At the same time, there is no corresponding screening system in the crushing process, and the uncrushed feed and dust in the feed cannot be screened out, thereby improving the quality of the feed. After the existing feed crusher is used, a large amount of feed residue will remain in the crusher. If it is cleaned manually, it is difficult to achieve dead-angle cleaning, and it is also dangerous. Therefore, a feed crushing and screening device that can screen uncrushed feed and dust, collect and re-crush uncrushed feed, and automatically clean feed residues is needed to solve the shortcomings of the existing feed crusher.

[0004] For example, the patent with announcement number CN104984784B provides a seed crushing device for a feed harvester, which includes a lower guide barrel, a seed crushing component, a sealing strip, an upper guide barrel, a transmission mechanism, and a spare guide barrel. The seed crushing component crushes the feed through two round rollers with teeth and rotating at high speed in opposite directions to achieve the feed crushing function. According to this application, most of the grains can be crushed after being crushed by the seed crushing component. Although this solution can achieve the crushing of most of the grains, there is still the problem of incomplete crushing. At the same time, this solution does not have corresponding secondary crushing or repeated crushing facilities, and it is impossible to crush the uncrushed feed again; although this solution can collect the crushed feed, it is impossible to screen and separate the dust, completely crushed feed and incompletely crushed feed; this solution also does not have corresponding anti-pinch and anti-stuck measures. When human hands or foreign objects enter the machine, if the foreign objects cannot be prevented from getting stuck in the machine, and the machine continues to operate at this time, it will cause a safety accident.

At this time, the feed particles will be blocked by the oblique filter plate 504, and the dust will pass through the oblique filter plate 504 and be blown out from the rear end of the suction pipe 503 to realize the feeding and preliminary filtering functions; when the feed particles enter the crushing shell 208 of the feeding mechanism, the first pulley 107 drives the third pulley 209 of the crushing device 2 to rotate through the first belt 8, and the third pulley 209 drives the feeding conveyor belt 207 and the feeding rotating shaft 210 to rotate counterclockwise, and the feeding conveyor belt 207 drives the vibrating screen component 7 to rotate counterclockwise through the fixing plate 206 and the clamping component 6, and the vibrating screen component 7 drives the feed particles The particles are first lifted upward, and at this time, the vibrating screen roller 704 will rub and roll on the inner surface of the crushing shell 208. The vibrating screen roller 704 drives the vibrating screen slide plate 702 to vibrate the feed particles back and forth through the vibrating screen connecting rod 703, so that the deflated particles and dust fall from the vibrating screen bottom plate 701, and then the fan blades 403 are driven to rotate by the third motor 404, and the dust and deflated particles are sucked out of the machine through the dust filter holes 402 on the dust filter plate 401, so as to realize the screening and separation function before the feed is crushed; then the feeding conveyor belt 207 drives the vibrating screen assembly 7 to continue to rotate counterclockwise, so that the feed particles on the vibrating screen assembly 7 are poured into the V-shaped groove 220, and at this time the second motor 205 on the longitudinal mechanism drives the third motor 205 to rotate through the third motor 205. The second belt 203 drives the second pulley 204 to rotate, the second pulley 204 drives the first worm 212 and the first gear 218 to rotate, the first worm 212 drives the first vertical roller 215 and the first transverse roller 219 to rotate synchronously through the first worm wheel 211 and the third belt 217, the first gear 218 drives the second gear 222 and the second worm 213 to rotate, the second worm 213 drives the second vertical roller 216 and the second transverse roller 221 to rotate synchronously through the second worm wheel 214 and the fourth belt 223, so as to realize the synchronous operation crushing function of the vertical mechanism and the transverse mechanism; the external threads on the first transverse roller 219 and the second transverse roller 221 will guide the feed to move forward, and the first The external threads on the vertical roller 215 and the second vertical roller 216 will guide the feed to move upward; when foreign matter enters during the feeding process, the vibrating screen bottom plate 701 will produce an obstructive effect after contacting the foreign matter and generate pressure on the locking slide 605 and the locking spring 602. The pressure will be transmitted to the pressure sensor 603 through the locking spring 602. When the pressure value on the pressure sensor 603 is too large, the electric push rod 604 will rebound immediately, so that the locking slide 605 can slide freely on the locking bracket 601. At this time, the vibrating screen bottom plate 701 can also rotate freely on the fixed plate 206, thereby realizing the anti-hand jamming and anti-foreign matter jamming functions; the moving wheel 201 on the support frame 202 is used for the moving function.
